This range is used only for those in extremely good physical condition during races or training for competition. It is typically used for interval training (or short sprints) to help improve or measure endurance levels. MONITOR YOUR PROGRESS Track yourself to determine how your overall health and fitness improves. As your cardiovascular system improves your normal resting heart rate will decrease. It will begin to take longer to reach your target zone and it will be easier to keep your heart rate steady during exercise. If you notice your resting heart rate higher than normal you should take a rest from exercise or at least workout easier that day. It may be an indication that your body has not completely recovered from a previous extraneous workout or injury. It could also be an indication of an illness coming on, stress, or a good reason for a check up with your doctor. ATTACHING YOUR HEART MONITOR 1. Attach the adjustable strap to one side of the transmitter. Push the round tab of the belt clip through the back side of the attaching hole on the transmitter and twist it into place (Fig. 1). The unique angled clip is designed to prevent the belt from slipping down your chest. It can be attached in either the up or down position (keeping both the same). Depending on the contour of your torso, one direction may be more comfortable than the other. Fig. 1 12 Belt Clip Transmitter Elastic Strap Fig. 2 2. Adjust the tension of the strap to fit snugly but comfortably around your chest. Wrap the belt around your chest as shown (Fig.2). 3. Center and position the belt as shown, at heart level, just below your pectoral muscles or breasts (but not too low) and attach the other end of the strap to the transmitter. The "Vetta" logo should be positioned at the center of your chest. Electrodes Fig. 3 4. Moisten the transmitter electrodes. For best results, the belt should be worn directly on your skin. A small amount of moisture is needed to assist in conducting the electrical impulses generated from your heart beats to the transmitter. Gently pull belt away from skin and apply a small drop of water or saline solution to each of the two electrodes (one on each side) (Fig. 3). If you prefer to wear your belt over a light shirt, you will need to generously moisten the areas of the shirt directly beneath the electrodes in order to insure proper signal pick-up. You may wear as many layers of clothing as desired over the transmitter belt without affecting the operating range. 5. Put your wrist monitor on. The monitor doesn’t have to be attached to your wrist to register your heart rate, it just has to be within 3 feet of your chest. 13 EXERCISING WITH YOUR HR409 HEART RATE EXERCISING WITH YOUR HR409 HEART RATE From Time of Day Mode click MODE button once to go to Heart Rate Mode and begin your exercise. If your transmitter is correctly attached, the running man indicator on the monitor display should begin to blink and your current heart rate in beats per minute will come up on the display. If no heart rate is detected for 5 min. the heart rate circuit will switch itself off. The indicator tells if the heart rate circuit is on. To switch it back on after it has shut off, simply restart the Heart Rate Mode by clicking the MODE button. THE TARGET ZONE Your monitor will provide both a visual indicator (by flashing the heart rate digits) and an audible alarm (beeping) if your heart rate is above or below your set target zone range. The "TZ" indicator with the or arrows will indicate if your heart rate is within, above or below the set target zone, respectively. The beeping alarm can be turned on or off by pressing the Alarm button (indicated by the on the display). TROUBLESHOOTING Can't get a Heart Rate reading? The most common cause for the heart rate not turning on or working erratically is that the belt is not positioned correctly or not moistened properly. Make sure that the belt is positioned high enough on your chest (too high is better than too low) and properly moistened. The tension should be comfortable but it shouldn’t be so loose that it slides down the chest. Also make sure that your monitor is within the 3ft. transmitting distance of the transmitter and check the angle of its position (at greater distances, the monitor face should be parallel and facing the transmitter, instead of on an angle). It is also known that a small percentage of the population may have trouble getting an accurate heart rate reading with this type of device due to the many various intricacies of the heart rate signal. The signal may be too weak on the surface of the skin, stronger in a different location of the chest or irregular in waveform. Also, if the user has had recent heart problems, surgery, or other various differentiating factors, they might cause a problem. If you are experiencing difficulties in picking up a steady signal, you may want to try your monitor on another person, or try positioning the belt higher on your chest, or shi...
